When it comes to the Olympics, the rankings are clear: the gold medalist is the top athlete, followed by silver, and finally, bronze.

The top athletes go for gold. If not gold, then silver is better than the bronze medal. But if that’s the case, why do medalists holding the bronze have a wider grin on their faces than the silver medalists?

How Olympic Athletes React Based On Which Medal They Receive

In a study comparing the reactions of medal winners, researchers took video recordings of the 1992 Barcelona Olympics. The first recording showed the athletes as they learned their placement and the second recording showed the medal winners standing on the podium.

Andre Agassi was living the dream. He traveled all over the world, had hordes of fans, and did something for a living that most people see as a hobby in their pastime. He boasts of being a former World No. 1 in tennis, an eight-time Grand Slam champion and an Olympic gold medalist.

Formerly married to actress and model Brooke Shields, Agassi’s life off court was as vibrant as his tennis performance. He would collaborate with brands such as Nike, Adidas, and American Express on multi-million dollar endorsement deals. Agassi was the ultimate sports star.

So why was he unhappy?

In his autobiography Open, Andre Agassi revealed that he hated tennis. He hated it with what he calls a “dark and secret passion”.

It’s easy to see why people lie to others: to keep their jobs, to avoid an argument with someone, to protect their reputation, or because they think everyone will be better off for it. It’s wrong, we know, but sometimes we figure that doing so is the best option in a sea of bad choices.

Lying to ourselves, though? It happens quite often, and as it turns out, we’re pretty good at it. We convince ourselves that we really need that new gadget, that we made a wise financial choice, or everything is fine (when it isn’t). Even if the evidence proves otherwise, we stick to our guns and refuse to back down.

More often than not, the lies we tell ourselves are harmful to our well-being and can be more damaging than we realize. So why do we do it?
